AI Technical Summary
Existing extraction processes for cannabis-based products face challenges in producing full-spectrum extracts that meet Good Manufacturing Practice (GMP) standards, often requiring downstream purification and using equipment like gas vapour compressors, which complicates compliance with pharmaceutical production requirements.
A closed-loop extraction system using a C1-4 fluorinated hydrocarbon solvent and rapid temperature control in a heating means to selectively extract cannabinoids and terpenes without unwanted molecules, eliminating the need for a vapour compressor and ensuring GMP compliance.
The system produces high-quality, full-spectrum extracts with minimal impurities, meeting GMP standards and eliminating the need for downstream purification, thus enabling classification as Botanical Drug Substances and pharmaceutical use.
